rel-(4R,5R)-5-(4-Chlorophenyl)-4-methyl-2-thiazolidinone CAS 78587-59-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including rel-(4R,5R)-5-(4-Chlorophenyl)-4-methyl-2-thiazolidinone.

CATO supplies rel-(4R,5R)-5-(4-Chlorophenyl)-4-methyl-2-thiazolidinone (CAS 78587-59-4), a certified reference material (molecular formula C10H10ClNOS, MW 227.71 g/mol) for analytical method development and quality control.

Structurally, rel-(4R,5R)-5-(4-Chlorophenyl)-4-methyl-2-thiazolidinone (C10H10ClNOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 227.71 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), rel-(4R,5R)-5-(4-Chlorophenyl)-4-methyl-2-thiazolidinone meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
